Realme will soon add a new smartphone under C-series that will be called Realme C21. The device name was a mystery until today, thanks to NBTC certification for confirming the moniker. Other than NBTC, the Realme C21 or its model number RMX3201 has appeared on multiple certifications sites (via) which includes Indian BIS, Wi-Fi Alliance, TKDN, EEC, and China Quality Certification website.
Getting plenty of certifications from multiple certification authorities hints that the device is nearing the launch. Realme C-series has always been affordable phone series, hence we expect the C21 to also fall under the affordable category. The device has also cleared BIS certification, which hints that Realme C21 will also launch in India.
There is not much known about the Realme C21, but certification reveals that it will boot Android 10 based Realme UI 1.0 at the top. The device supports 2.4GHz WiFi 802.11 n/b/g connectivity, and 10W of normal speed charging.
